Long stroke and soft impact

Self-Compensating, Soft-Contact
Energy capacity 975 in-lbs/cycle
Stroke 1.58 inch

Ideal for soft damping: the SC found in the model code from the ACE product family SC190 to SC925 stands for 'soft contact'. These miniature shock absorbers manufactured from one solid piece are designed in such a way that they can be setup with a linear or a progressive braking curve. The soft damping character is thanks to the special, long strokes which produce smooth deceleration and low reaction forces.

These maintenance-free, ready-to-install hydraulic machine elements are equipped with an integrated positive stop. The use of side load adapter allows impact angles of up to 25°. Thanks to the designed overlapping effective weight ranges, these dampers cover an effective load range of 3 lbs. to 4,400 lbs! Self-compensating shock absorbers react to changing energy conditions, without adjustment.

These miniature self-compensating shock absorbers from the SC190 to SC925 product family are used in industrial, automation and machine engineering and primarily in the areas of handling and automation.

Application Examples

SC190-925 - Damping on rotary movements
SC190-925 - Damping on rotary movements
ACE miniature shock absorbers optimize production with minimum expenditure. The cycle rate for an assembly line producing electronic components was increased to 3,600 units/hr. Miniature shock absorbers type SC190-1 decelerate the rapid transfer movements on the production line and using soft damping methods optimize the pick up and set down of components. This soft deceleration technique has ...

SC190-925 – Quadrocopter protected with miniature shock absorbers
A team of students have fitted a quadrocopter with miniature shock absorbers as part of a robotics project. So that they did not have to deal with costly repairs and downtimes during the study of flight characteristics and whilst learning about the craft’s handling, the future graduates installed ACE type SC650M-0 miniature shock absorbers on both the top and the bottom of the helicopter. ...
